Feature Comparison

Mapping

Unlike robots that don’t have a map and move randomly until the battery runs out, Roomba navigates efficiently. It moves back and forth in straight lines methodically covering the cleaning area based on the map it generates.

Both vacuums use camera sensors and odometry to map the layout of your home and store 10 maps in memory.

Digital blockers.: If there is a room that might not be ready for cleaning or a zone where you have cords, etc., you can set an unlimited amount of digitally blocked areas and no-go lines. Once you have done it, the robot will not cross it. You can create a zone by drawing a rectangle or setting the tape (no-go line) on a place you don’t want the robot to cross.

Clean area With this option, you can create a rectangle on the map to make the robot work in the selected area.

The selected housekeeping completes the cleaning, it will generate a map divided into separate rooms. You can merge or split the area as you like if you don’t like the way the robot did.

Controls
